FLUSHlNG-VALVE FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 311,026. dated January 20, 1885.

Apulication fied June 10. 1882.

To all whom it may concern:

Be it known that I, MICHAEL T. F. ODoN- NELL, a citizen of the United States, residing at Boston, in the county of Suffolk and State 5 of Massachusetts, have invented certain new and. useful Improvements in Flushing-Valves for Water-Closets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

{ making part of this specification, in which Figure 1 is a perspective view of the flushing-valve when in use. Fig. 2 is a vertical section of the same. Fig. 3 is a side view of the bridge and a port-ion of the spindle. Fig.

[5 4 is a top view of the cup portion or seat of the valve.

My invention relates to certain improvements in flushing-valves for water-closets, and has for its object to produce a steady, rapid,

and uniform flow of the water to the flushingrini without undue noise or whistling.

To this end my invention consists in the combination, with a valve-seat and weighted valve, of an overflow or stand pipe secured to said valve, a bridge-piece on the under side of the valve, communicating through the same with the stand-pipe, and provided with one or more air ports or apertures, through which the air entering at the top of the stand-pipe is 0 discharged above the top of the valve-seat when the valve is raised, to enable it to mingle with the water passing through the valve, and thus facilitate its flow, the bridge-piece being provided with a spindle projecting down from 5 its under side and passing through a guide connected with the valve-seat, by which construction and arrangement of parts the irregular and spasmodic flow of the water common in flushing-valves of the ordinary con 0 struction is avoided, as hereinafter more particularly set forth.

In the said drawings, A represents the overflow or stand pipe, which is secured at its lower end to the valve B, having a gasket or 5 packing of leather E, which is kept in place preferably formed of lead, which is secured to the top of the valve B, to accelerate the descent of the same and keep it firmly on its (No model.)

Iseat. The valve B, which is hollow and communicates with thes'tand-pipe A, as seen in Fig. 2, is provided on its under side with a bridgepiece, B, preferably cast in one piece .with the valve, and having one or more airports, I), for the discharge of air or water which may overflow from the tank into the standpipe A at its top.

F is aspindle which projects down from the under side of the bridge-piece B and passes through a guide, I, extending across the bottom of the valve-seat O, as seen in Figs. 2 and 4, whereby the valve as it rises and falls is kept in its proper central position with respect to the valve'seat O, which is to be soldered or otherwise secured to the bottom of the water-tank, and connected with the pipe which supplies the flushing-rim of the Watercloset.

To the upper end of the spindle F, which extends up within the pipe A, is pivoted a rod, G, the upper end of which is to be connected to a lever, (not shown,) by means of which the valve is to be raised to produce the flow of the water to the flushing-rim. By pivoting the rod G to the spindle F as shown the upper end or mouth of the pipe A is left free and a brace or other piece were applied to the top of the pipe to serve as a means of connecting the rod G thereto; and, furthermore, this method of connecting the rod to the standpipe prevents the spindle F from binding in the guide I. When the valve is at rest and unused, it occupies the position seen in Fig. 2. On the valve being raised into I the position seen in Fig. 1 the water from the tank rushes into the hollow portion or seat 0, and passes rapidly to the flushing-rim of the water-closet, the air entering the top of the pipe A, and being discharged through the ports b of the bridge-piece B above the level of the top of the valve seat, which causes it to mingle with the water passing through the valve in such manner as to lessen the resistance to the passage of the water and produce a steady and uniform flow of the same to the point where it is to be used. As soon as the pressure on the lever attached to the rod G is removed the valve B is returned to its original position by the weight D.

I find in practice that, to attain the best reunobstructed, which would not be the case if sults, the stand-pipe A, when used as an air escape or influx, must be of not less than onehalf the diameter of the valve seat or portion 0 through which the water escapes from the tank, otherwise it will not practically avoid the irregular and spasmodic admission or egress of air, and will produce an unpleasant noise or whistling as the water escapes, which it is very desirable to avoid.

I am aware of the United States Patent No. 167,265, dated August 31, 1875, and British Patents Nos. 2,451 of 1860, and 941 of 1879, and hence make no broad claim to a standpipe connected with the valve, and serving as an overflow-pipe for the tank, and also as a downward conductor for the air. My invention, however, difi'ers from all of these in having a hollow bridge-piece connected with the valve and stand-pipe, and provided with one or more air ports or apertures located directly beneath the movable valve B, whereby when the latter is raised the air is discharged above the top of the valve-seat, to enable it to mingle with the water as it first enters the valve,

thus producing a more perfect and uniform flow of the water than where the air is discharged below the level of the valve-seat.

What I claim as my invention, and desire to secure by Letters Patent, is

In a flushing valve for water closets, the combination, with the valve-seat O and the weighted valve B, of the overflow or stand pipe A, open at its upper end and secured to said valve, a bridge-piece, B, on the under side of the valve and communicating through the same with the stand-pipe, and provided with one or more air ports or apertures, I), through which the air entering at the top of the stand-pipe is discharged above the top of the valve-seat when the valve is raised, and the spindle F,projecting down from the bridge piece and passing through a guide, I, all constructed and arranged to operate substantially in the manner and for the purpose set forth.
